This part is listed by BMW as BMW part number 11537642854 (11 53 7 642 854) and is described as the Heat Management Module for the B58 engine used in F22 M240i, F30 340i, and F32 440i. It's also for 2017-2019 models of the G30 540i, G12 740i, G01 X3 M40i, and G02 X4 M40i. These cars use the B58A engine. The Heat Management Module takes the place of a traditional thermostat.

Your engine's thermostat regulates coolant flow and temperature in the cooling system. When open it allows hot coolant to flow into the radiator to be cooled. When closed the coolant circulates through the engine, where it stays warm. A failed thermostat will either be open or closed with the engine running too cold (poor fuel economy and performance) or too hot (overheating). It can also impact your cabin heating/cooling since that system is drawn from your heater core.

This is a Genuine BMW cooling module with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.
